Hello, when is it expected to be available for sale on an exchange?

Hello, today I came across the news about a new ASIC miner for ETH.
Linzhi Phoenix ETH Miner 2600 MH/s ASIC for ETH mining
2600 MH/s / 3500W

The only place where it is offered is this site  https://cryptominersoutlet.com/product/linzhi-phoenix-2600-mh-s-8g-memory-new-in/

I think it's fake news because the price is very low.
For comparison, the price of the Innosilicon A11 Pro 8GB 2000Mh is around € 18,000
